12 is a. vertical sectional view taken on the line 12-12 ofiig. 3, end v Fig. 13 is e perspective view of one of the wedge blocks.

In the drawings the numeral 10 designotes a. vertically split housing comprising complementory members. The housing members are secured together by bolts ii and nuts 12. By em ploying four bolts the housing may be resdllv and easily assembled or disossenobled. Suitable necking strips 13 are interposed between the sold peckhousing members.

The housing includes a. horizontal ennuler fiance is below which is located a lower peck ing chamber 15 and above which extends on upper packing chamber 16. The flange is suitable for supporting the device in. e. casing head as is shown in Fig. 1. The lower packing chainber 15 will be below the top of the cosine heed v end thus the projection of the device shove soiol head will be reduced.

The lower packing chber has diametrically opposite guides 17 (Figs. 2 end 7) which receive sliding wedge blocks 1e resting against upright shoes 19. The shoes have their rear faces flat to receive the blocks and their iront feces conceved to embrace opposite sides of o cylindrical is member or sleeve 20 fitting in the lower chber.

Adjusting screws 21 ere threaded through the flange ot the e angles es the outer wells of the guides 17. Each wedge block it hos s kev slot 22 (Figs. 2 and it) ior recei the lower end of one of the screws, whereby the blocks are suspended in the guides. By rotating the screws blocks are slid downwardly and lnwerdlv, thus displacing the shoes 19 inwardly end coin pressing the packing sleeve ob rut the cubic, rod, tube or other element which passes through the device. Hold-down jews M are located on eech side oi the housing for securing it sgoinst upword displacement."

"the housing is formed with a vertical shank w 23 extending upwardly from the fiance it end in which the upper necking chamber i6 is food. The flange has n reduced opening 24 through which the cable posses and thus sold 7 he forms o top .ior the lower positing chem m ber, whereby the sleeve 2c is retained.

The upper packing chamber 16 has an inclined annular bottom 16' and receives a cylindrical packing sleeve 25, which will more closely embrace the cable or other element which it surrounds, when forced down said inclined bot tom. The packing sleeve 25 is formed of rubber or any material suitable for the purpose and while various types of cylindrical packing members could be used I prefer to use the sleeve herein set forth. The sleeve is split vertically one side to its bore 26 (Figs. 11 and 12), while on the opposite side it is split nearly to its outer wall to form a vertical hinge, whereby the sleeve may be opened as is shown in Fig. 11 for engaging it around a cable, rod or tube as the case may be.

A particular feature of the packing sleeve is an annular incision 2'7 inclined downwardly from its outer wall, but terminating short of its bore 26 so as not to sever the sleeve. A follower sleeve 28 slidable vertically in the chamber 16 rests upon the packing and when forced downwardly compresses said packing about the cable as well as forcing it down the inclined bottom.

It is obvious that the downward pressure on the packing sleeve will cause the upper portion to ride down the inclined surfaceof the lower portion provided by the inclined incision 27. The thin wall uniting the upper and lower portions of the packing will soon be worn through by the cable. This arrangement will compensate the wear of the packing sleeve and with the inclined bottom 24, will bring about an equal gripping of the cable or rod throughout the length of the bore 26. Grease pockets 29 may be provided in the bore 26. The same kind of packing may be used for the sleeve 20 thus avoiding the making of two styles of packing sleeves.

The shank 23 of the housing has vertical diametrical slots 30 above the packing sleeve 25. The follower sleeve is provided with diametrically opposite ribs 31 engaging said slots. These ribs terminate short of the bottom of the sleeve and have outwardly directed lugs 32 at their bottoms (Fig. 4).

The sleeve 28 has a vertical door 33 hinged thereto (Figs. 4, 5 and 6) which when opened exposes the bore and permits the sleeve to be placed on a cable or other cylindrical element. Ears 34 are provided at the top of the sleeve on each sideof the ribs.

These ears support bolts 35 on which grooved guide pulleys 36 are journaled on each side of thebore of the sleeve. The bolts are secured by nuts 37. By removing the bolt 35 above the door 33 the pulley 36 thereabove may be removed and the sleeve easily placed on the cable. The guide pulleys act to center the cable or other element in the sleeve.

One of the features of the invention is means for depressing the follower sleeve 28 to compress the packing sleeve 25. Some mechanism involving the element of leverage, whereby quick as well as gradual and forceful action is most desirable. The housing is provided on each side of the shank 23 with upright standards 38 spaced therefrom andopposite the slots 30.

Segmental gears 39 are journaled on studs 40 extending from the standards to the shank. Each gear has a hug 41 bearing against the shank for spacing said gear therefrom and also has a cam 42 adapted to engage one of the lugs 32 to depress the follower sleeve. When the cams 42 are in theirupright position their flat sides are substantially parallel with the slots 30 and thus the lugs 32 are free to pass vertically when the follower sleeve 28 is lifted from the shank 23.

For actuating the cams the segmental gears 39 are employed and these gears are swung by pinions 43 fastened on the end of a counter-shaft 44 journaled in brackets 45 extending from the shank 23. A worm gear 46 is fastened on the shaft 44 between the brackets 45. A worm screw (Fig. 2)

47 meshes withand drives the gear 46 and is .journaled on a stud 48 screwed into a boss 49 extending from the top of the shank. A hold-down keeper 50 secured to the brackets 45 bridges over the hub of the worm screw 47 and a crank handle 51 is made integral with the screw for revolving the same on the stud 48.

The segmental gears each have their teeth so regulated that when the pinions 46 engage in the last tooth, the parts will be locked against further movement except in a reverse direction. When this occurs the cams 42 will be in the position where their fiat sides are substantially parallel with the slots 30, whereby the parts are automatically positioned for inserting and removing the follower sleeve 28. It is obvious that by revolying the crank handle 51 the countershaft 44 is rotated and the segmental gears 39 are likewise rotated. The gears may be quickly rotated or swung and as they are swung the cams 42 have their curved sides brought into engagement with the lugs 82.

I The upper edges of the lugs 32 are rounded so as to induce the cams to ride thereon. As the cams move downward the lugs 32 are carried downward, thus depressing 28, whereby the packing 26 is compressed. When the pinions arrive at the lowermost teeth on the segments. the packing will have been completely worn out and further downward movement of the sleeve 28 will be prevented. The operator will thus know that the packing must be replaced. 7

When it becomes necessary to replace the upper packing 26 it is merely necessary to run down the screws 21 to displace the blocks 18 and compress the lower packing 20. This will prevent the upward escape of fluid while the upper packing is being replaced. In replacing the upper packing the parts are manipulated to bring the cams 42 tothe position shown in full lines in Fig. 8.

The sleeve 28 is then elevated and the split packing 26 is placed around the cable and dropped into the shank 23. After this is done the sleeve 28 is again lowered and the crank handle 51 operated to actuate the gears 39 and compress the packing 26. After the packing 26 has been compressed the screws 21 are backed up to release the packing 20, the use of which is no longer required. f

It will be seen that by reason of the worm gearing and comparatively large segments considerable leverage is had and. therefore, the earns 42 will depress the sleeve'28 with ample force. The device may be easily and quickly operated and as it is only necessary to handle five bolts, including the bolt 37, the saver may be quickly mounted or dismounted.

The term cable" has been used generically herein because the device could be used on rods or tubing as well as upon a cable. Various changes in the size and shape of the different parts, as well as modifications and alterations. may be made within the scope of the appended claims.
